Title: Cutoff and transfer mechanism for web-rewinder
IPC: B65H19/22
Filed: 1969-06-06
Abstract: 1,211,500. Feeding webs. PAPER CONVERTING MACHINE CO. Inc. 6 June, 1969 [24 July, 1968], No. 28783/69. Heading B8R. A web cut-off and transfer mechanism for a turret winder includes a rotatable snubber roll which, at the end of a winding cycle, is moved into contact with the web to snap it, rather than cut it, whilst simultaneously urging the new leading edge of the web against a glue-equipped core on a mandrel just entering the winding station of the winder. As shown, one rotating mandrel 17 of a turret 19 having other mandrels 18, 25, 26 carries a core C on which is wound a roll R of a transversely perforated web, e.g. toilet tissue. The web W passes through embossing rollers 11, 12, over a perforating bedroll 13, under a driven roller 15 and over a bar 16 to the core C. A driven roll 20 carrying a pad or snubber 24 is mounted on arms 21 which pivot on the shaft carrying the roller 15 and which oscillate, when so urged by a connecting rod 23 associated at its lower end with a cam arrangement 48, 49, from the position 20 to the position 20<SP>1</SP>; a system of gearing (Figs. 3 and 4, not shown) between the cam arrangement 48, 49, the perforating bedroll 13, the roller 15 and the snubber roll 20 ensures that the movement of the arms 21 and rotation of the roll 20 are synchronized with the perforating action of the bedroll 13. Thus, when the roll R has reached a predetermined size the snubber roll 20 is moved into position 20<SP>1</SP>; the pad 24 holds the web W against the glue-equipped core on the new mandrel 18 and as the surfaces of both the roll 20 and core C are moving in a direction opposite to the direction of web travel the web snaps along a perforation-line between cores 17 and 18, leading edge developing a reverse fold which is urged into contact with the new core C. A further roller 59 is provided to apply adhesive to the web so that the tail T formed by the severing action may be glued on to the completed roll R1.

Title: Improvements in machines for stretching and brushing hanks of yarn
IPC: D06C19/00
Filed: 1919-11-24
Abstract: 137,512. Hermans, D. Jan. 10, 1919,. [Convention date]. Yarns, brushing and stretching; hanks, treating.-The hanks are passed over a fixed roller 44 and a loose roller 48, and are brushed by a rotary brush 46. During the brushing operation, the hanks are stretched by a weighted lever 4 which is connected by an adjustable link 35 with the arm 36<1> of a lever, the other arm 36 of which carries an adjustable bearing 37 for depressing the lower roller 48. The arm 36<1> carries a cam surface 39 which, during the downward movement of the arm 36, operates a lever 41 and link 42 so as to raise a " hook lever " 43 and cause the axle of the lower roller 48 properly to engage with the adjustable bearings 37 on the stretching- lever 36. The means for releasing the weighted lever 4 for applying tension to the hanks and raising it for releasing them, comprises a nut 7 on a screw 6 which is rotated in one direction or the other through reversible friction wheels 12, 14 driven from the loose pulley. In starting the machine, the strap is on the loose pulley and drives the friction wheels 12 which are disengaged from the friction wheel 14 on the screw 7. One or other of the friction wheels 12 is then placed in gear with the wheel 14 by operating a weighted hand-lever 19 provided with side catches for retaining it in its acting position. The rotation of the screw 7 causes the movement of the levers 36 and 43 so that the axle of the stretching-roller will be gripped to the hanks placed under tension; simultaneously, the nut 7 on the screw 6 operates a disengaging rod whereby the weighted lever 19 is disengaged from its holding-catch and the lever assumes a middie position with the friction wheels 12, 14 disengaged. The strap is then plaoed on the fast pulley and the brushing proceeded with. At the termination of the brushing operation, the strap is transferred to the loose pulley and the weighted lever 19 operated so as to cause the friction wheel 14 to rotate in the direction required to raise the weighted lever 4, release the tension roller 48, and ultimately release the weighted hand-lever 19, when the hanks may be removed from the roller 44, 48 and replaced by fresh ones.
